Project Cases

Highway service area domestic wastewater treatment project:Processing capacity :400m³/d.Raw water quality: High content of COD, BOD, NH3 and total phosphorus.Solution: Underground package wastewater treatment plant.Process: a. Wastewater is collected by collecting pipe network.b. Wastewater flows automatically to bar screen channel, and the large floating matters would be removed by the coarse bar screen.c. Wastewater would enter the primary sedimentation tank through oil separation tank for sedimentation of non-dissolved matters.d. Wastewater flows automatically into the regulating tank which homogenizes the water flow and quality.e. Through sewage pump, water would enter the underground package wastewater treatment plant, through biological absorption and degradation, the pollutant would be removed and the water can reach the effluent standard.
